Was It Stop Leak?
Well I was wrong about this being stop leak on the gasket as pointed out (the first person to point it out) Vipermech. It appears that it was really a gasket prep material. I still stand by my assessment of stop leak products, follow the directions if you are going to use them but I hope this update will also help educate about NOT using anything on a head gasket when you install it.
